Micro Controls
Several years ago, Trane was the first to
introduce microprocessor controls into
the Light Commercial Market. That
design, along with immeasurable
experience, has provided the technology
for Trane’s second-generation ReliaTel
™
microprocessor controls.
ReliaTel Micro:
• Provides unit control for heating,
cooling, and ventilating by utilizing
input from sensors that measure
outdoor and indoor temperature.
• Improves quality and reliability through
the use of time-tested microprocessor
controls and logic.
• Prevents the unit from short cycling,
considerably improving compressor
life.
• Ensures that the compressor will run
for a specific amount of time, which
allows oil to return for better
lubrication, enhancing the reliability of
the compressor.
• Reduces the number of components
required to operate the unit, thereby
reducing possibilities for component
failure.
• Eliminates the need for field-installed
components with its built-in anti-
short-cycle timer, time delay relay
and minimum ‘’on’’ time controls.
These controls are factory tested to
assure proper operation.
• Requires no special tools to run the
Precedent unit through its paces
during testing. Simply place a
jumper between Test 1 and Test 2
terminals on the Low Voltage
Terminal Board and the unit will walk
through its operational steps. The
unit automatically returns control to
the zone sensor after stepping
through the test mode a single time,
even if the jumper is left on the unit.
• As long as the unit has power and
the LED is lit, the Micro is
operational. The light indicates that
the Micro is functioning properly.
• Features expanded diagnostic
capabilities when used with Trane’s
Integrated Comfort
™
systems.
• As an energy benefit, softens
electrical ‘’spikes’’ by staging on fans,
compressors and heaters.
• The Intelligent Fallback or Adaptive
Control is a benefit to the building
occupant. If a component goes
astray, the unit will continue to
operate at predetermined
temperature set points.
• Intelligent Anticipation is a standard
feature of the Micro. Functioning
constantly, the Micro and zone
sensors work together in harmony to
provide tight comfort control.
